Ohmite’s TAP800 Series dis-
sipates 800 watts of power
when used with a liquid or
air cooled heat sink system.
The TAP800 rounds out 600
watt (TAP600) and 1000 watt
(TAP1000) product offerings.
Applications include variable
speed drives, power supplies,
robotics, motor control, con-
trol devices, and other power
designs.
FEATURES
• Electric support is high alumina
content ceramic metallized on
the bottom for ideal heat transfer
and optimum discharge.
• Encapsulated with a special
resin filled epoxy casing with
a large creepage distance to
mass, large air distance between
terminals, and a high insulation
resistance (CTI 600).
• Resistive element is specially
designed for low inductance
and capacitance. The element
provides stable performance
in addition to high wattage and
pulse loading capability.
• Contacts allow for easy load con-
necting with M4 or M5 screws
(not included).
• Materials meet the requirements
of UL94-V0
